When previewing an essay or other reading assignment, you should (B.) read the title, subtitle and author's name.

Previewing is a strategy used when working with a piece of writing. It consists in skimming a text before doing a full reading in order to grasp a general idea of that text.  Moreover, it involves reading only specific information such as the title, the name of the author and the headings instead of reading the complete text in detail. Readers generally resort to previewing in order to improve comprehension.
